What’s the best way to simulate accurately the bandwidth of a ring resonator? Lately, I’ve been doing it manually from the transmission of the ring.
I have found the bandwidth is very dependent on the simulation time. For a 3 micron ring, even 20,000 fs doesn’t seem enough for the bandwidth to converge. It finally converges around 75000 fs on my case. (3 micron ring, 0.2 micron coupling gap for the standard Si ring resonator model)
